To all 'whom it mayoncem: i"

Be it ,known that I, WEBER R. DUNKEL, a citizen of thel UnitedStates', residing at `Pana, in the county `of Christian and State of Illinois, have invented a new anduseful -Automobile-Primer, ofwhich the following is 'a specification.

v- This invention* relates ytio` fi'nte,rnal com;

.bustion engines, and more especiallyto they starting ,devices thereofy which apply a combustible mixture to thecylinders; andthe n object of the same is to produce a primer Aby means of whichall the cylinders can bel instantaneously Iprimed with raw. or free gasoleie in charges which can be adjustedy .according to thefrequirernents of each cylLAK inder.

To' thisend the inventan consists ia the 52- construction,hereinafter: setforth and claimed, and .as shown yin the drawings r wherein-.

- -..Figure.1is a side elevation of the engine of an automobile with my improved primer attached; Fig. 2 is an enlarged vsection' throughone.. of the measuring valves,- and .its parts; Fig.y 3 is avertical 'section on the ienne s e of Fig. e; Fig. its a horizontal sectionon the line lll-4: of Fig. 2; Fig. 5 is I' a section on the line 5 5 of Fig. 2; Fig.-6 .is a detail of the switch attached to the dash-i board- In the drawings is shown part of an automobileA, having four cylinders C, and Gr designates a pipe' for conveying gasolene to the pet cocks'I. which are now commonly for priming purposes.l

Coming now more particularly to the present invention, the gasolenej pipe G leads over the various pet cocks "which stand in. a row and is-conne'ct'edfwithv each of them through an inlet port ,5 andother means liest vseen in' Fig. 2, and? the lbore/6 of each pet cock leads down through .its yscrewn threaded lower end 7 whichfengages in and through the wall of the cylinder in a manner well understood.` The body of this pet cock forms the casing 8 of a measuring valveV whose plug 9 is tapered externally as shown, and has a transverse opening or bore 10.v adapted to register with the bore 6 Within the pet cock. VSaid plug also has a longitudinal bore 11 communicatingwith the' transverse bore 10 and thus forming a 'If-shaped measuring chamber within the the engine.

inserted in the upper ends of the cylinders lplug, one end yof the boreill being internally' threaded as at 12 to receive a'threaded plug A13 having a nick 14 in its outer end which e Patented Apr.' 2', 1912.

may be reached with va line screwv drivery f through the open endv 15 of the. plug4 9.

`Obviously when `this plug is adjusted forward or backward the size ofthe measuring l chamber within the .plug vmay be regulate asdesired.l .IniFig 2 the bore/1Q vwhich l forms" the shank 4ofthisT-shaped chamber stands uppermost ready to receive gasolene vthrough the-Inlet port from the tube G, and 1t is obvious-that when thel lug isl given a yhalf revolution by means o the-switch illustrated in Fig. 6 the bore l0 will be moved fromthe inlet. around to the outlet portionof the'bore. 6 and the charge of gasolenewill beemptied into the; cylinder' for priming the latter. This is the construction at the head of all the cylinders of Both extremities of the plug 9 are slotted as shownat 20 and thev forks of the slots pierced with holes vforsplit pinsy 21 or other fastening meanswhereby the various plugs are connected as by plates 22, preferablyv havin@ slots 23 which looselyy enga e saidl fastening means 21. Connected with the slot of the rearmost plug is a rod 24 which passes through the dash-board and isv secured .to a ,handle 25 by turning which the operator may manipulate fall ofthe valves at once. Around the smaller 'end of. each plug screws a nuty26 against awasher 27 lwhich latter is tongue-and-grooved as at 28 as's'hown inl Fig. 5 sol that it will not rotate when the nut is, set up,l and the adjustment ofthe latter isobviouslyu for the purpose of drawing the; conical plug' more closely into thecasing S'Iwhen it commences to leak, the slot 23. in plate 22 permittin individual adjustment if it be found toy necessary. Moreover it isiclear that the screw plugs? 13 can-be individually adjusted when it is latterF with a source of gasolene supply; of 4 a measuring valve for each'l pet cock consisting of a plug seated in said openingv and having a T-shaped chamber whose shank Aregisters with said `bore in either of two positions,

both ends of all plugs being slotted, plates engaging the slotted ends of adjacent plugs,

' and means for simultaneously turning the connected series of. plugs. J
